Understanding Nutrition and Balanced Diet
Nutrition is the process by which our bodies take in and use food to maintain life. A balanced diet is one that provides all the essential nutrients in the right amounts for proper growth and development. It includes carbohydrates, fats, proteins, vitamins, minerals, dietary fibres, and water. Eating a balanced diet helps our body function properly and stay healthy. It is important to include a variety of foods in our diet to ensure we get all the necessary nutrients.

Food Groups and Their Functions
Food can be grouped into different categories based on the nutrients they provide. Carbohydrates, such as cereals, vegetables, and fruits, are the primary energy sources. Fats, found in nuts, seeds, and oils, also provide energy and help in the absorption of vitamins. Proteins, from pulses, beans, and animal products, are essential for growth and repair of the body. Vitamins and minerals, found in fruits, vegetables, and dairy products, protect our body from diseases and keep us healthy. Dietary fibres, mainly from plant products, help in digestion and waste removal.

Digestion: From Mouth to Intestines
Digestion is the process by which food is broken down into smaller components that can be absorbed and used by the body. It starts in the mouth, where teeth and saliva begin the breakdown of food. The food then moves to the stomach, where it is further broken down by stomach acids. From the stomach, the food moves to the small intestine, where most of the nutrients are absorbed. The remaining undigested food moves to the large intestine, where water is absorbed, and the waste is prepared for elimination. Understanding this process helps us appreciate the importance of chewing food properly and eating a balanced diet.

Healthy Eating Habits and Mindfulness
Healthy eating habits are crucial for maintaining good health. This includes eating a variety of foods, chewing food properly, and avoiding overeating. Mindful eating involves paying full attention to the eating experience, without distractions like TV or phones. It helps us enjoy our food more and prevents overeating. Eating locally grown and plant-based foods is also beneficial for our health and the environment. It is important to drink sufficient water and include dietary fibres in our diet for proper digestion and waste removal.

Common Nutritional Deficiencies and Prevention
Nutritional deficiencies occur when the body does not get enough of a particular nutrient. Common deficiencies include Vitamin A deficiency, which can lead to poor vision and night blindness, and Vitamin C deficiency, which causes scurvy and slow wound healing. Iodine deficiency can lead to goitre, and iron deficiency can cause anaemia. To prevent these deficiencies, it is important to include a variety of foods in our diet, such as fruits, vegetables, dairy products, and proteins. Regular medical check-ups can also help detect and prevent nutritional deficiencies.

Q2. What are the primary functions of carbohydrates and fats in our diet?
Show model answer
Model answer
Carbohydrates and fats are primary sources of energy in our diet. Carbohydrates provide instant energy, while fats serve as stored energy. They help us perform various activities and keep us warm in cold weather.
Sample question3 marks
Q3. Describe the role of saliva in the digestion process.
Show model answer
Model answer
Saliva is produced in the mouth and contains an enzyme called amylase. This enzyme helps in breaking down starch into sugars, which are simpler molecules that can be used by the body for energy. Saliva also moistens the food, making it easier to swallow and digest.

Q4. What are three healthy eating habits that can help maintain a healthy body?
Show model answer
Model answer
Three healthy eating habits include eating a balanced diet with all essential nutrients, avoiding junk food, and eating locally grown and plant-based food to the extent possible. These habits help in providing the necessary nutrients, maintaining overall health, and reducing environmental impact.

Q5. What is scurvy and how can it be prevented?
Show model answer
Model answer
Scurvy is a disease caused by a deficiency of Vitamin C. It can be prevented by including citrus fruits like lemons and oranges in the diet, as they are rich sources of Vitamin C.
